2.4 tonnes/cubic meter
Yes, you need to know the density of tarmac which varies depending on the aggregate used but is around 2.4 tonne per cubic metre
Tarmac Limited's population is 12,500.
Tarmac is short for tar-penetration macadam.
Tarmac Limited was created in 1903.
If we didn't have Tarmac roads the roads would be bumpy and dusty, the dust would go in to the air and cause people to cough and could cause crashes. The inventor of Tarmac is Edgar Hooley he invented Tarmac in 1902. Tarmac is heated and then poured on to road.
When installed, tarmac is a mixture of solid aggregate in liquid asphalt. When the mixture cools, the finished tarmac pavement is solid.
Only if... (a) you know the weight of a measured amount of tarmac - and (b) you know what depth the tarmac is. If you can calculate the volume of tarmac, and you know the weight of a specific amount - you can convert to tonnes.
in 1830 the Scotsman John Loudon Macadam invented the first form of tarmac called Tarmacadam. the tarmac we know today was made in 1901.
Tarmac is not a rock, but a man-made road surfacing material.
In 1901, tarmac was patented by Edgar Purnell Hooley. Hooley named it after John MacAdam, giving it the name Tarmacadam, which most everyone shortens to tarmac.
